This way values such as maxrate/bufsize can be utilized further
down the chain.
The libavcodec values are utilized instead of from the encoder
configuration struct since:
1) both utilize bits per second, so no loss of precision occured.
2) the struct defaults various values to nonzero - even though it
is documented to be unused outside of bit rate based rate
control modes.
